First, a sodium fluoride solution, which is a fluorine component, is applied to the surface of the mouthpiece 10 formed by folding the base material 1 with the nonwoven fabric 1A side as the surface. Specifically, the sodium fluoride solution is evenly applied to the first joint portion 20, the second joint portion 30 and the third joint portion 40 (maxillary joint portion 40a and mandibular joint portion 40b).

Subsequently, the occlusal surfaces of the teeth on the maxillary side and the occlusal surfaces of the teeth on the mandibular side of the third joint 40 are occlusion, and the occlusal surfaces of the teeth on the maxillary side are connected to the maxillary joints 40 a of the third joint 40 . , and the occlusal surface of the tooth on the mandibular side is joined to the mandibular joint portion 40 b of the third joint portion 40 .

At this time, the first joint portion 20 is joined to the surface of the tooth on the maxillary side along the tooth row on the maxillary side, and the second joint portion 20 is joined to the surface of the tooth on the mandibular side along the tooth row on the mandibular side. The part 30 is joined.

Thereby, as shown in FIG. 5 , the mouthpiece 10 is worn in the mouth of the wearer P with the ion introduction portion 50 protruding from the wearer's P lips. At this time, since the mouthpiece 10 is bonded over the entire main parts of the teeth, such as the surfaces of the teeth and the occlusal surfaces, it is possible to appropriately prevent dental caries of the wearer's P teeth when used for dental treatment, for example. be able to.

In the present embodiment, after about 4 to 5 minutes have passed with the mouthpiece 10 worn by the wearer P in the oral cavity, the mouthpiece 10 is worn over the entire teeth of the wearer P. Calcium fluoride is formed by the action of the sodium fluoride solution applied to the wearer P, and is then replaced by fluoroapatite, so that remineralization of the teeth is promoted, so that the dental caries of the wearer P can be properly prevented.

Moreover, since the mouthpiece 10 of the present embodiment is formed using the base material 1 configured using a versatile material, it is assumed that it can be mass-produced easily and inexpensively.
